Shotgun with full size sound moderator (silencer) at the Abu Dhabi International Hunting and Equestrian Exhibition

just seen this as i was away when you posted it. no unfortunatly its not mine, it was an action that was at paul roberts show rooms/work shop when i was in havin a look. i only had my phone to take the photos and they dont do justice at all compared to looking at it for real......the detail is unbeliavable . i would hazard a guess from prices quoted in the past to me that the cost of that engraving on that action alone, would pay for a new box lock double rifle from a known english gunmaker.........
